Does this planet have a “sibling” sharing the same orbit?
Using ALMA,
astronomers have found
a possible “sibling” to a planet
orbiting the distant star PDS 70.
Planet – Sibling
The team detected a cloud of debris
in one of the regions of the planet’s orbit
where a “sibling” planet would be expected to exist
trapped by the gravity of the star and the planet.
The debris could be the building blocks of a new planet,
or the remnants of a planet already formed.
If confirmed this would be
the strongest observational evidence yet
that two planets can share the same orbit.
